Tungsten Copper WCu Kub dab dej
Kev piav qhia
Tungsten tooj liab hluav taws xob ntim khoom muaj ob qho tib si tsis tshua muaj zog ntawm tungsten thiab siab thermal conductivity ntawm tooj liab.Dab tsi yog qhov tseem ceeb tshaj plaws yog tias nws cov thermal expansion coefficient thiab thermal conductivity tuaj yeem tsim los ntawm kev kho qhov muaj pes tsawg leeg ntawm cov khoom coj los yooj yim.
FOTMA siv high-purity thiab high-zoo raw cov ntaub ntawv, thiab tau txais WCu hluav taws xob ntim cov ntaub ntawv thiab cov khoom cua kub dab dej nrog kev ua tau zoo heev tom qab nias, high-temperature sintering thiab infiltration.
Qhov zoo ntawm Tungsten Copper (WCu) Cov Khoom Siv Hluav Taws Xob
1. Cov khoom siv tungsten tooj liab hluav taws xob ntim khoom muaj qhov hloov tau thermal expansion coefficient, uas tuaj yeem sib xyaw nrog cov substrates sib txawv (xws li: stainless hlau, valve alloy, silicon, gallium arsenide, gallium nitride, aluminium oxide, thiab lwm yam);
2. Tsis muaj sintering ua kom cov ntsiab lus ntxiv kom tswj tau cov thermal conductivity zoo;
3. Tsawg porosity thiab zoo huab cua nruj;
4. Zoo tswj qhov loj me, nto tiav thiab flatness.
5. Muab daim ntawv, tsim qhov chaw, kuj tuaj yeem ua tau raws li qhov xav tau ntawm electroplating.
